The BWV Numbering System is a method of ordering and labeling the various works of the classical artist Johann Sebastian Bach. BWV stands for "Back-Werke-Verzeichnis", which is German for "Bach Works Catalog".
circa 1734
The German catalogue number of a JS BACH work is called Bach Werke Gezeichnis (abbreviated to BWV). So Cantata N°4 has been catalogued in 1950 as BWV 4, for example. When the Catalogue was revised to include rediscovered works, the was added an Appendix (in German : Anhang, abbreviated to Anh.) So there are Apocryphal Bach Motets assigned the Catalogue numbers BWV Anh. 159-165.

BWV -not BMW- stands for Bach-Werke-Verzeichnis ("Catalogue of Bach's Works"), made and published by musicologist Wolfgang Schmieder in 1950, and thoroughly updated in 1990. Every known musical work by Johann Sebastian Bach has been assigned a BWV number in his catalogue.
J.S. Bach composed more than 1100 songs if we count from BWV.
Wikipedia shows the manuscript of the first sonata (BWV 1001) is autographed from 1720. One could possibly assume that all the third partita (BWV 1006) was composed around the same time.
